eemR (version 1.0.2)

eem_export_matlab: Export EEMs to Matlab

Description

Export EEMs to Matlab

Usage

eem_export_matlab(file, ...)

Value

A structure named OriginalData is created and contains:

nSample

The number of eems.

nEx

The number of excitation wavelengths.

nEm

The number of emission wavelengths.

Ex

A vector containing excitation wavelengths.

Em

A vector containing emission wavelengths.

X

A 3D matrix (nSample X nEx X nEm) containing EEMs.

sample_name The list of sample names (i.e. file names) of the imported EEMs.

Arguments

file

The .mat file name where to export the structure.

...

One or more object of class eemlist.

Known bug in export

eemR uses R.Matlab to export the the fluorescence data into a matfile. However, there is currently a bug in the latter package that require the user to reshape the exported data once in Matlab. This can be done using the following command: load('OriginalData.mat'); OriginalData.X = reshape(OriginalData.X, OriginalData.nSample, OriginalData.nEm, OriginalData.nEx)

Details

The function exports EEMs into PARAFAC-ready Matlab .mat file usable by the drEEM toolbox.

Examples

file <- system.file("extdata/cary/", package = "eemR")
eem <- eem_read(file, recursive = TRUE, import_function = "cary")

export_to <- paste(tempfile(), ".mat", sep = "")
eem_export_matlab(export_to, eem)
